FREDERICK KELLY, OF TORONTO, ONTARIO, CANADA.

HOT-PRESSED-NUT-MAKING IWACHINE.

To all whom it may concern:

Be it known that I, FREDERICK KELLY, of the city of Toronto, in thecount-y of York, in the Province of Ontario, Canada, have inventedcertain new and useful Improvements in Hot Pressed Nut Making Ma.-chines, of which the following is the specification.

My invention relates to improvemel'its in hot pressed nut makingmachines, and the object of the invention isfirstto devise a machine ofthis class in which the bar will be sized before it passes into themachine, and thus insure the perfect formation of the nutsecondly-toprovide an improved feeding means, whereby the bar is carried forwardunder the shears preparatory to the formation of a nutthirdly-to form anut completely finished and thus dispense with the after finishing of anut now commonly incident to machines of this classfourthlyto deliverthe shot, bur and the nut separately and therefore obviate the presentnecessity of sorting and thus dispense with a vast amount of labor andconsequently greatly reduce the cost of operating the machine--fifthlytoso construct the machine as to reduce the wear and tear to a minimum onthe tool and consequently reduce the repair on the same to a minimum andthe cost of operating the machine and seventhlygenerally to greatlyincrease the capacity of the machine as compared with other machines ofthis class at present in use.

To effect these objects I have constructed my improved nut makingmachine in the manner, which I shall now presently describe andillustrate in the accompanying drawings forming part of thisspecification.

Figure 1, is a perspective view of my improved nut making machine takenfrom the side in which the bar is fed into the machine. Fig. 2, is aplan View of the machine complete.

Fig. 31 is aplan'view showing the nut in position after it is punched.

In the drawings like letters of reference indicate corresponding partsin each figure.

Alis the frame of the machine, which comprises the bed proper A, thelegs A the lower side bars A and the front side bar A and the back sidebar A 'B is the main driving shaft and B the main driving pulley and Bthe hub of the pulley. The shaft B is journaled in suitable bearings G Csecured to the projecting rear portions A forming part of the bed A.

D is a bevel gear wheel secured at the opposite end of the shaft, whichmeshes with the bevel gear wheel E on the end of the shaft F, which isjournaled in suitable bearings G G secured to one side of the bed A.

From the shaft B is driven the feed, the

top sizer, the front hammer, the punch, the

crown kicker and the main kicker for discharging the nut when formed andthe back hammer when used to make a square nut. From the shaft F isdriven the side sizer, the side hammer and the relief mechanism inconnection with the feeder.

I shall first describe the means whereby the bar is sized prior to beingfed into the machine.

A is a block forming part of the bed. A is a plate located to the backof the block A and held in position by set. screws (See Fig. 3).

A by a bolt 2 (see Fig. 7) and abutting the plate A The bed I has asemi-dove tail tongue I, which fits into a correspondingly formed recessI in the bed A slightly larger than the dove-tail. The set screw Iextends through the side of the bed A (see Fig. 5) against the straightside of the dovetail, and thereby serves to hold the supplemental bed Iin position. A supplemental hold-fast screw I is also tends through thebed I. The bed I has an upwardly extending flange I to which thesemi-dove-tail guide-way I is secured by suitable set screws I and boltsI J isthe sliding bed, whichis held between the guide-way I andguide-way I forming part. of the bed I. I is a recess made in one sideof the bed I and having fitted therein the stationary bottom K of thesizer. K is the stationary side of the sizer, which extends partiallyover the bottom K and is secured in posit-ion by a plate K held by boltsK 'The sliding bed J is provided with a recess J through which extendsthe upper end of the lever J which is held in suitable ways J 3 formingpart of the lower provided which exend of the lever J 4 which isfulcrumed on a bracket J attached to one of the bottom bars of the frame(see Fig. 7).

L is a pitman, which is connected at one end to the lever arm L, whichis hung on the counter-shaft 13* operating in connection with the mainshaft B as will hereinafter appear. The opposite end of the pitman Lextends through guiding notches A in the frame.

' J is a block having end projections J rounded at the inside andabutting the sides of the wall of the lever J The block J extends into achannel bar L forming portion of the pitman L, the ends being providedwith slots J through which bolts J 9 extend in order to permit theadjustment of the lever.

' J is a set screw for adjusting the position of the block J.

J is a fiat spring secured to the bottom bar A of the frame andconnected by a hook bolt J to a portion of the lever J The tendency ofthe spring J is to exert a forward pressure on the lever J and to takeup lost motion.

M is the'front former, which is secured in position by the cap plate 1Wsecured in position by the bolts 1 The front end of the former isprovided with a notch M in this instance, of the form of the majorportion of a hexagonal nut.

N is a feeding way into which the bar Z is inserted from which the nutis formed. The feeding way extends from the face of the bed A to thesizing bar, the stationary ones of which have been already described.One side N of the feeding way is formed by a step in the bed A and theopposite side is formed by the side of the supplemental bed O. Thesupplemental bed 0 is held from longitudinal displacement by end clips 0secured to the side of the bed by bolts 0 The bed 0 is formed with alongitudinal groove 0 and a dove-tail groove 0 immediately above it.

C) is a feeding bar, which is provided with an end slot 0 into whichextends the spring 3 secured at the bottom to the side of the frame. Thefront end of the bar 0 is provided with a T-shape cross head 0 formedwith a guide-way and said bar 0 is also provided with a notch O in thefront end of which is pivoted on a pin 0 the T-arm O (see Fig. 9).

O is a slot in the feeding bar into which extends the upper end of thelever 1 which is shown in Fig. 7 and corresponds in every respect to thelever J 4 hereinbefore described in reference to Figs. 1, 5 and 7, withthe exguidinggroove 0 at the top of the bed 0. The plate 0 is cut awayat one side as indicated and is provided with a slot 0 opposite the slot0 O is a notched arm pivoted on the pin O and engaging normally with theupper end of the lever P.

O is a stationary bracket attached to or forming part of the plate 0 O"is a lever pivoted in a fork at the inner end of the bracket 0 andhaving a jaw at the outer end connected at its inner end with the arm 15by a pin 0 extending through the arm 0 into the plate Q A spiral spring0 extends between the lever O" and the bracket 0 and normally serves tohold the pin in the plate O and the notched arm 0 in engagement with theupper end of the lever P. By depressing the outer end of the lever O thearm 0 may be disengaged from the upper end of the lever P for a reason,which will appear hereinafter.

The inner end of the feeding bar is provided with a bar extending acrossthe feed ing way N and having a feeding nib 0- extending upwardlytherefrom.

O is a plate affixed to the top of the feeding bar, and designed to forma rest for the nut bar 75*. When worn it may be readily replaced.

U is a guide way secured at the outer end of the cross head 0 by bolts0. The head 0 is provided with a recess 0.

O is a plate fitting between the guideways 0 and O and carrying thefeeding nib 0 preferably made of hardened steel let into the plate 0(see Fig. 8).

The T-end of the bar 0 is connected by a link 25 to the head 0 and by alink 0 to a pin extending from the bottom of the plate 0 As the lever Pis caused to move forward it carries with it the plate 0 and T-bar 0,thereby straightening out the links 0 and 0 more into alinement witheach other and thus forcing the feeding nib 0 into contact with the barZ from which the nutis made, and pressing such bar Z against the feedingnib 0 As the lever Pis still caused to move forward it carries with itthe bar 0 and as the bar Z of iron from which the nut is made is alreadygripped by the nibs O and 6 it will be fed forward I a requisitedistance to place it in position for the making of a nut. The movementnecessary to impart to the lever P to effect this object is provided forby a cam Q (see Pi s), which is located on the main shaft B and co-actswith a roller Q] adjustably held on the end of the lever arm Q fulcrumedon the shaft B and having the lower end connected by a pitman Q to thelever P.

The style of connection of the pitman Q to the lever P is the same asthat described of the pitman L to the lever J The pitman Q is,'however,adjustably connected to the lever arm Q by means of a screw spindle Qwhich extends upwardly into a slot Q in the lever arm in which is held ablock Q to which the end of the pitman Q is pivotally connected. Thelower end of the screw spindle is provided with collars Q one on eachside of the end of the lever arm and the end of the screw spindle issquare. As the screw spindle extends through a corresponding thread inthe block Q it will be readily understood that by turning the screwspindle the desired adjustment or throw of the pitman is effectedsuitable for the work. The roller Q may be also adjusted as it isjournaled in bearings on the end of the slide Q which is held inguideways on the end of the lever arm by the bolt Q9 extending through aslot Q in the slide. A set screw Q, ex tends through a boss Q and abutsand holds the roller in the desired position relative to the cam Q.

As hereinbefore premised and as shown in the drawing the shaft rotatesin the direction indicated by arrow and movement is imparted to thelever P by the cam Q. The first movement is a quick movement, so as tothrow the lever inwardly and feed by means of the nib O. The retrogrademove ment of the lever is more gradual as far as the operation of thecam is concerned but hastened by means of the spring 3, which acts onthe outer end of the slide the movement, however, being controlled bmeans of the face cam F secured to the end of the shaft F and co-actingwith the lever F having a roller F engaging with the cam, and theopposite end engaging with the outer face of the upper end of the spring3. The lever F is fulcrumed on a bolt ex tending upwardly from a bracketF attached to the bed A.

It will be seen that if it is desired to stop the feed in case of adefect in the nut bar 7r, or on account of any part of the machinegetting out of order the lever 0 may be thrown so that the notched levermay he brought free of the lever P and thus cause the lever to move freein the slot 0 The front former M hereinbefore described is manipulatedthrough a pitman L, which is connected to a lever arm L, the upper endof which is provided with a guide-way L in which fits a bar L having a.roller L journaled in jaws at the lower end thereof. A bolt L extendingthrough a slotted hole in the bar holds the bar L in position and byunloosening the bolt and adjusting the set screw L the roller may beadjusted to and from the cam L with which it co-acts (see Figs. 1, 5 and10).

L is a guide-way made in the off-set L forming part of the lever arm L.

L is a slotted bar held in the uide-way L by a suitable headed bolt L 6L is a set screw, which extends through the closed end of the guide-wayand abuts the end of the bar L By unloosening the bolt L1 the bar L maybe adjusted to and from its co-acting cam L The cam. L acting with thebar L serves to impart as will readily be seen a movement of the bar Lin the direction indicated by arrow, thereby throwing the lever J andconsequently the front former Mforward to carry the nut forward from theposition in which it is held in the notch in the V former shown indotted lines in Fig. 9, to a point past the punch R, where the nut dropsas will hereinafter appear.

The cam L co-a-oting wlth the roller L serves to restore the former toits normal position ready to receive the next nut from the side formerby pulling upon the pitman L in the opposite direction to that indicatedby arrow and thereby throwing the lever J 2 and former in the oppositedirection.

The bar is fed in over the supporting roller 4 attached to the bedopposite the feeding way N- This roller is shown re- 'moved in Figs; 1and 8.

.a corresponding recess K at the top and at' one side of the bed A, thetongue being heldfin position by a set screw K. The bar' .K is providedwith slots K and K and a plate K fits over the top of the bar K and issecured in position by bolts K and K extending through bolts K and Irespectively. A slot K is made in the plate K and a'pin K extends" intothe bar K* through said slot, the pin K being con nected by a spiralspring K to the bolt K The inner-end 'ofthe bar K extends over the 5.feeding bar .0 in the slot 0 of which works the T-arm 0 (see Figs. 1, 2,3, 7, 8 and 9). The bar K is shown broken away in Fig. 9. The end of thebar K is formed 7 with a step K on which is secured a har- 55 denedsteel block K by a plate'K held in position by a'bolt K This steel blockis the block that is actually brought'against the bar Z from the side tosize it. The bar K is provided at the opposite end with a hardened blockK which is secured on a step byla bolt K In order to impart the desiredforward movement to the bar K I provide a lever K which is 'journaled ona bracket K secured to one of the bottom bars of the frame. The upperend of the lever K is provided with a jaw K in which is journaled aroller K. K is a collar secured to the shaft F and carrying a cam K,which when the shaft rotates in the direction indicated by arrowoperates against the roller K and thus imparts the necessary length ofmovement to the bar K hereinbefore referred to. The spring K serves toprovide for the retrograde movement, and take up the lost motion.

I shall now describe the means by which the top sizer is driven so as tosize the bar Z from which the nut is made.

S is a standard secured to the top of the bed plate A.

S is a lever pivoted on a spindle S held in the standard S.

S is a sizer bar and S a block preferably of steel T-shaped in crosssection, which fits and is suitably held in the lower end of the sizerbar, which is formed in an L or angle-shape, so that the base of the Lextends over the feeding way in order that the block may be brought downagainst the bar Z previous to its being fed to the shear. The sizer barS is bolted to a bar S, which is held in suitable guide-ways S securedto the front of the standard S by a cross dovetail connection S.

S is a forked link between the members of which extend the forward endof the lever S. The lower end of the link S is connected to the upperend of the bar S by a cross pin S and between the upper end of the bar Sextends a block S which is provided with an arc-shaped recess at thebottom to fit the top of the bar S and an arc-shaped recess S at the topinto which fits a roller S The roller S extends into a similar recess atthe bottom of the front end of the lever S (see Fig. 4). A set screw Sis provided with a suitable lock nut and extends through the top of thelink S and abuts the front end of the lever and thereby holds the link Sconnected to the lever S (see Figs. 1, 8 and 11). The rear end of the.lever S co-acts with a cam S, which also operates the return movement ofthe front feed. Such cam is secured on the shaft B (see Fig. 2), therear end of the lever\S and the cam being similar to the rear end of thelever and cam shown in Fig. 18, and designed to operate the front kickeras will hereinafter appear. In the initial stage the bar Z is fed byhand over the roller 4: until it comes opposite the sizing devices.

I have described the manner in which the bar Z is fed and this feedingtakes place immediately after the bar Z is sized. The feeding device nowbrings the bar Z forward after ,being sized so that the end of the bar Zis opposite the shear, which I designate 5. The shear 5 is held in thestock or socket 6 by a holding plate 6. The stock 6 has formed behind itan inclined chute 6 and a plate 6 right angular in form (see Figs. 20and 24) having a groove 6 formed at the longer vertical side and agroove 6 formed at the upper short vertical side and a groove 6 formedat the lower short ver.. tical side. As shown in Fig. 13, 7 is a plateextending upwardly through an opening in the bed A. and secured to thestandard S. The plate 7 is provided with a corresponding tongue 7 intowhich the groove 6 fits, a corresponding tongue 7 into which the groove6" fits and a corresponding tongue 7 in which the groove 6 fits, therebyproviding for a rigid strong light way to insure the vertical upwardmovement of the shear. The bottom of the stock (3 has secured to orforming part of it a depending lug 6 to which is pivotally connected alink (3 The requisite movement of the shear is imparted to it by meansof a heavy lever 6, which is journaled on a stud shaft (3 held in thedepending jaw 6 suitably secured and held to the bed A (see Fig. 4). Asteel angle plate 8 is securely bolted at the front end of the lever andhas an arc-shaped upper boss 8, which fits into a corresponding recessat the bottom of the link 6 A leaf spring 8 is secured to the bottomforward end of the lever and is designed to hold the front end of thelever up, the pressure necessary for this purpose being regulated by aset screw 8 extending through a strap A The rear end of the lever haspressing against it a spring 8 which is secured to the back side bar Aof the frame. The upper rear end of the lever 6 is provided with a notch6 in which is secured a bar 6" having an end aw carrying a roller 6. Thebar 6 is secured in position. by a suitable bolt 6 passing through aslotted hole in the bar 6 and provided with a suitable nut. The positionof the roller 6 is adjusted by means of a set screw 6 extending throughthe lever 63 opposite to the end of the bar 6 6 is a bar having aninclined upper end, such bar being secured in position by a bolt (2passing through a slotted hole in the bar and being adjustable by a setscrew 6 passing through a boss 6". The bar 6 is located to the innerside of the bar shown in Fig. 4. The roller 6 co-acts with the cam 9,which is a quick pitch cam and the inclined end of the bar 6 co-actswith the cam 9, which is also a quick cam of less radius than the cam 9and having a concentric portion for a purpose which will hereinafterappear. The cam 9 is also formed with a concentric portion but theportion of the cam which operates the shear is practically an acuteangle. The shear 5 co-acts with the shear block 10, which is providedwith an orifice 10 having a crowning cap l 10 concaved beneath it andprovided with a central orifice 10 Into this orifice extends a verticalspindle 10 through a top plate 10 (see Figs. 11, 12, and 13).

10 is an arm secured to the shear lever 6 10 is an arm secured to theshaft Such arm 10 is held in a stationary position and has pivotallysecured to it the link bar 10 which is connected by a link 10*.

to the free end of the arm 10 10 is a cam secured on the shaft B. Thecam 10 operates against the projection 10 forming part of the bar 1 22to insure the full return movement of the shear lever ready for the nextoperation.

The spindle 10 extends through an orifice l0 in the plate 10 dove-tailin cross section and fitting into a corresponding groove in the top ofthe shear block 10 and serving to hold the crowning block 10 inposition. The form of the orifice 10 is, where a hexagonal nut is to bemade, hexagonal in shape and the block 10 is provided with a divideddie-block 10 having half of the hexagonal formed at each side, the dieblock being formed with dove-tail tongues at the side to fit into acorresponding groove 10 in the shear block, which terminates at one endnear the side of the shear block. Each half of the divided die-block 10is provided with a semi-hexagonal notch 10 (see Fig. 15) which togetherform a hexagonal opening through which the shear is designed to pass,the shear in this particular case being also hexagonal in cross section.The die block 10 is a loose fit in the groove 10 so that it may bereadily inserted therein, but is held rigidly from the side by means ofpins 10 having beveled inner ends, the outer ends projecting beyond theside face of the block. The pins 10 are pressed inwardly by means ofplates 10 secured in position by set screws 10 (seeFigs. 13, 14c, 15,16, 22 and 23). The die block 10 is held against the closed end by asupplemental block 10 secured in position by plates 10 abutting the endsof the block 10 and secured in position by set screws 10 (see Figs. 6and 15). The lever 6 through the roller 6 cooperating with the cam 9forces the shear 5 upwardly against the bar Z from which the nut is out(see Fig. 11) the inner end of which is opposite the inner face of theshear and severs the nut, which in this case is hexagonal in form, andforces it up through the die block. The tri-angular pieces necessarilyleft at the extreme ends (for the end of the bar Z is necessarily atfirst rectangular) when they are severed drop behind the shear holder 6on the incline chute or way 6 (see Fig. 20 and in dotted lines in Fig.6) and thence passes downwardly to the chute 11 where this refuse isdischarged. The shear 5 passes up through the die block 10 carrying withit the nut into the position shown in Fig. 12 at which point the roller6 of the lever 6 has reached the apex of the cam, thereby crowning thenut as indicated in Fig. 12, against the crowning block 10 At this pointthe cam 12 on the collar 12' (see Figs. 2, 4 and 6) co'acting with thelever 14 fulcrumed on a pin S in the standard 2 and adjustable block 1 1at the front end thereof operates the kicker rod 10 and frees the crown,the kicker rod having been previously raised by the shear forcing thenut upwardly into the crowning block 10 The roller 6 now having passedover the apex of the cam 9 the inclined end of the bar 6 co-acting withthe cam 9 keeps the lever stationary as it runs on the concentricportion of the cam 9 and therefore the shear stationary when the nutdrops back into the position immediately above the die block. The top ofthe shear is then level with the top of the block. At this point theside former is operated as I shall presently describe. v

I provide a shield 10, which extends over the top of the guiding plate 6to which the shear is attached as hereinbefore described. The shield isL-shaped in cross section and the holding plate 6 moves up between itand .the back of the guide-way. The shield serves to prevent any piecescut from the bar from passing above the plate.

The plate 10 hereinbefore referred to is a divided plate being providedat the lower end with a notch 10 at the abutting edges of the plates. Agravity latch 10 is located in a groove 10 at the end of the shear block10 being held in position by a pin 10 extending through a slot in thegravity latch. The head of the latch fits in the notch 10 when it is inthe raised position. The bar Z of iron from which the nut is made passesunder this gravity latch, which necessarily is to the front of theblock, and when the bar has been fed in to the full extent and all thebar has been practically used up the latch drops down behind theremaining part of the bar Z and prevents it being fed backwardly againwhen the feeding bar is caused to recede. The shear punches the nut fromthis end and the refuse then drops down through the machine. It will benoticed that the head of the latch is beveled, so that thenext bar fedin will raise it as it passes on to the position above the shear andbeneath the die.

When the nut is located above the die block subsequently to beingcrowned as hereinbefore described it is necessary that the nut becarried from such position to a position in the notch M of the frontformer in order that the hole may be punched, from the center of the nutto complete it. To effect this purpose I provide a side former T adaptedto enter the recess M of the frontformer M having a notch T at the innerend. The former T is held in a holder T located between suitableguide-ways T. The holder is supported at the bottom on a plate T havinga semi-dove-tail tongue at the bottom fitting into a correspondinggroove in the bed A and held therein by a set screw T A cross bar T isprovided, which has end trunnions to which is connected the side links TThe opposite end of the side links are pivotally connected to a pin T atthe upper end of the lever U, which is fulcrumed at the bottom on abracket U secured to one of the side bars of the bottom of the frame.The lever U has j ournaled in a recess in the upper end thereof a rollerU which co-acts with a cam U secured on the shaft F. A roller U isprovided, which is journaled between the two sides of the extensionframe U secured to the lever U. A pin II on both sides of the cam Ucontacting with the upper end of the frame U serves to start thebackward movement of the former. The cam U rotates in the directionindicated by arrow and being connected to the holder T as hereinbeforedescribed a reciprocatory movement is imparted to the side former, so asto intermittently and at the proper moment carry the nut struck out bythe shear into the notch M underneath the punch R, which derives avertical reciprocating movement in the manner I shall presentlydescribe, so as to punch a hole in the center of the nut when it is heldbetween the notch M in the front former and the notch T in the sideformer.

The shot is carried down through a tubular conduit W and delivered to aseparate receptacle (not shown) see Figs. 5 and 6. The tubularreceptacle or conduit IV extends to the top of the bed A and die blockW, which is secured in the block W suitably held in the bed by setscrews, such as W A stripper W" having an orifice W extendingtherethrough is provided, which is secured in position on the deadformer W adjustably held above the block by a set screw W. The punch, ofcourse, passes through this orifice and is stripped as it recedes (seeFig. 13). The stripper "W is secured in position by the set screw W andby the vertically slidable bar IV held in a suitable guide-way. The barIV is provided with slots W and V and a projecting pin W extendingthrough a slot W in the cap plate W W and W are bolts extending throughthe plate Vi and through the slots W and into the back of the way.

W is a set screw securing the bar W in position against the stripper. Byloosening the set screw W the bar may be raised to free the stripper.
